The term "shinte" 新手 (new move) refers to the creation of new moves, moves that were never played before in this situation. In go it is used for a play that deviates from current joseki but is a candidate for becoming joseki.
There is a well known motto of Kozo Masuda (famous 9-dan shogi player): "Shinte issho" (lifelong quest for new moves).
Bob McGuigan: See the quote of Kikuchi in Old Mottos
